Low insertion-loss SP4T RF switch chip is RoHS-compliant

Lowell, Mass.— Slated for antenna switching applications in cellphones, M/A-COM 's RoHS -compliant (Restriction of Hazardous Substances in Electrical and Electronic Equipment) SP4T (single-pole 4-throw) switch comes in a PQFN (power quad flat leadless) package. The MASW-007813's lead-free 3-mm 16-lead PQFN packaging can streamline space requirements and save cost.

Ensuring linearity while reducing DC power, the MASW-007813 is conventionally used in multi-switching systems that operate on a single antenna. These include GSM (Global System for Mobile) communication handsets.

High Power-Handling

The MASW-007813 switch is designed to maintain linearity up to 3-GHz, while ensuring switching at levels to 38-dBm output power. It exhibits a typical insertion loss of just 0.6-dB. Its IIP3 (third order input intercept point) spec is 57-dBm.

For those of you interested in what's inside the package, the SP4T switch is fabricated in a 0.5-micron gate-length GaAs (gallium arsenide) pHEMT (pseudomorphic high electron mobility transistor) process. The GaAs pHEMT device is fully passivated for reliability. It's also fully high-power RF-tested to ensure performance compliance.
